A discount lowers the price a customer pays at checkout. Because Macropay is your merchant of record, you set the promo and we handle the rest: the sales tax / VAT is recalculated on the discounted total, remitted on your behalf, and your tax liability stays capped. Discounts work the same way on one-time products and on subscriptions, so a single coupon can power a launch sale, a partner offer, or a win-back campaign.

​
Create a discount

Open the Products page in the dashboard and switch to the Discounts tab. Each discount is defined by a few fields.

​
Recurring behavior

For subscriptions, choose how long a percentage discount keeps applying:
  • Once — applied to the first invoice only.
  • Several months — applied for a fixed number of billing cycles, then full price resumes.
  • Forever — applied indefinitely for the life of the subscription.

​
Restrictions

Tighten where and when a discount can be redeemed:
  • Products — limit the discount to specific products. By default it covers every product, including ones you create after the discount.
  • Starts at — the discount becomes redeemable on this date.
  • Ends at — the discount stops being redeemable after this date.
  • Maximum redemptions — cap the total number of times the discount can be used.
Pair Maximum redemptions with Ends at for a true “first 100 customers before Friday” launch offer — once either limit is hit, the code stops working automatically.

​
Apply a discount

There are three ways to get a discount onto a customer’s checkout. When you build a Checkout Link, you can attach a discount that applies the moment a customer lands on the page — no code to type, no chance they forget it. This is the cleanest path for a campaign where you want the price guaranteed: a Product Hunt launch link, an affiliate partner’s URL, or a newsletter promo.
Code-less discounts can only be applied through a Checkout Link or the API. If you want customers to enter a coupon manually, give the discount a Code.

​
2. Prefill a code via query parameter

Append a discount_code query parameter to any Checkout Link to prefill the coupon field:
This only fills in the field — the customer still sees the code in the form and can change or remove it. Use it when you want the offer visible (and editable) rather than silently baked in.

​
3. Apply programmatically via the Checkout API

Create a Checkout Session and pass the discount yourself. Handy for AI agents and apps that assemble a personalized cart — for example, an upgrade flow that grants a loyalty coupon based on a customer’s usage:
See the Checkout Session reference for the full payload, including how to pin the discount so the customer can’t swap it out.
However a discount is applied, Macropay stays the seller of record on the customer’s statement and remits the correct tax on the discounted amount — you never reconcile VAT against a coupon yourself.
